SAFETY lCE-CREEPER.

SPECIFICATION forming part of Letters Patent No. 593,315, dated November 9, 1897. Application filed May 14,1297. Serial No. 636.598. (No a To aZZ whom it may concern:

Be it known that we, ERNST LOUIS WAGNER and ANNA FRANZISKA WAGNER, subjects of the Emperor of Germany, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Safety Ice-Creepers, which improvement is fully set forth in the following specification and accompanying drawings.

Our invention consists of a safety icecreeper which is so constructed that it can be quickly and expeditiously adapted to be Worn out of doors on icy pavements and streets or it can be readily turned into inoperative position when indoors, so that there will be no liability of injuring carpets; and for these purposes it consists of the novel details of construction, as will be hereinafter fully set forth, and pointed out in the claim.

Figure 1 represents a plan view of a safety ice-creeper embodying our invention,the same being shown in position for application of a heel thereto and being turned into inoperative position. Fig. 2 represents a bottom plan view of Fig. 1. Fig. 3 represents a section on line a: m, Fig. 1, but showing the spurs turned from the position seen therein into operative position or for use when out of doors. Fig. 4 represents a plan view of Fig. 3.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates the base of a safety ice-creeper, the same having the rim or wall B, which projects upwardly therefrom and is adapted to conform'to the contour of the heel O, the terminals of said wall being provided with spurs D, which engage the heel of the wearer in substantially the manner indicated in Fig. 3.

E designates a lug or extension located at the back of the creeper and adapted to engage the rear portion of the heel C, said lug having passing therethrough the screw or other similar fastening device F, which is turned into engagement with the heel G.

G designates a movable plate which is located in advance of the base A and is pivotally mounted in the walls B by means of the journals H, said plate being provided on the side thereof with the spurs J, which in the present instance are three in number, and are arranged in staggered order, although such arrangement, as well as the number of the spurs, can bevaried.

K designates a plurality of flat springs, which are slightly bent or bowed, as seen in Fig. 3, each of which have one end secured to the base Av by means of pins L or other fastening devices, while the free ends M of said springs bear uponthe plate G.

N designates a finger-piece attached to a suitable portion of the plate G for the purpose of manipulating the latter, said fingerpiece seating in the recess P (best seen in Fig. 2) when the plate G is turned into the operative position seen in Fig. 3.

. Q designates a depressed portion or seat in the plate Gfor the purpose of making a joint with the base A, as will be understood from Fig. 3.

The operation is as follows: The creeper is secured to the heel C in the manner indicated in Fig. 3 by means of the screw F and the spurs D. When it is desired to use the same out of doors on icy pavements, streets, &c., the plate Gis turned into the position seen in Figs. 3 and 4, the same being held therein by means of the springs K. When it is not desired to use the spurs J, the plate Gis turned into the position seen in Figs. 1 and 2, the same being retained therein by means of the springs K, the creeper being now. adapted to be worn in the house, 850.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

A safety ice-creeper consisting of a base with a rim having the recess P therein, a pivot-ed plate mounted in said rim and having a finger-piece adapted to enter said recess, springs secured to said base and bearing against said plate, spurs on said plate, and means connected with said rim for securing the same to a boot or shoe heel, said plate having a depressed portion adapted to abut against the under side of said base.
